Abstract (en)
[origin: EP1045004A1] There is provided a vinyl chloride resin composition, which is excellent in processability and can produce a processed article having excellent physical property or a formed molding having excellent property. A processing aid having specific viscosity of at least 0.5 is combined with a vinyl chloride resin, wherein the aid is obtained by polymerizing 1 to 50 parts by weight of a monomer mixture (B) comprising 0 to 49 % by weight of methyl methacrylate, 51 to 100 % by weight of at least one monomer selected from the group consisting of a methacrylate ester except methyl methacrylate and an acrylate ester, and 0 to 20 % by weight of a vinyl monomer copolymerizable therewith, in the presence of a latex of a (co)polymer having specific viscosity of at least eta sp 0.7, which is obtained by polymerizing in emulsion 99 to 50 parts by weight of a monomer mixture (A) comprising 51 to 100 % by weight of methyl methacrylate, 0 to 49 % by weight of at least one monomer selected from the group consisting of a methacrylate ester except methyl methacrylate and an acrylate ester, and 0 to 20 % by weight of a vinyl monomer copolymerizable therewith, wherein the total amount of (A) and (B) is 100 parts by weight.
